[0040] Traditional pulse diagnosis devices lack a structure for locating the patient's wrist. During pulse diagnosis, after the patient places their hand on the device, the cun, guan, and chi positions on the patient's wrist are often misaligned with the device's probes or sensors. This usually requires the physician to manually align the cun, guan, and chi positions with the probes or sensors, making the device inconvenient to use.

[0041] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 1 This is a schematic diagram of the structure of the diagnostic system 1000 provided in the embodiments of this application. Figure 2 This is a front view of the pulse acquisition device 100 provided in the embodiments of this application. Figure 3 This is a schematic diagram of the pulse acquisition device 100 provided in the embodiments of this application. Figure 4 This is a cross-sectional view of the pulse acquisition device 100 provided in the embodiments of this application. Figure 5 This is an exploded view of the airbag module 31 and the detection module 32 provided in the embodiments of this application. Figure 6 This is a schematic diagram of the structure of the support member 40 provided in the embodiment of this application.

[0042] In the embodiments of this application, for the purpose of clearer description, Figure 2 and Figure 3For reference, in this application, the X-axis is defined as the length direction of the pulse acquisition device 100, the Y-axis is defined as the width direction of the pulse acquisition device 100, and the Z-axis is defined as the height direction of the pulse acquisition device 100. The length direction X, width direction Y, and height direction Z of the pulse acquisition device 100 are set perpendicular to each other.

[0043] This application provides a diagnostic system 1000, which includes a diagnostic device 200 and a pulse acquisition device 100 as described in any embodiment of this application. The pulse acquisition device 100 is communicatively connected to the diagnostic device 200. The pulse acquisition device 100 is used to detect pulse signals at the cun, guan, and chi positions on the wrist of the patient to be tested, in order to detect the pulse of the patient. The pulse acquisition device 100 is also used to transmit the detected pulse data to the diagnostic device 200, so that the physician can determine the pulse condition of the patient based on the output of the diagnostic device 200.

[0044] The pulse acquisition device 100 includes a base 11, a mounting base 12, an airbag module 31, a detection module 32, and a support member 40. The mounting base 12 is connected to the base 11. The arrangement direction of the mounting base 12 and the base 11 is parallel to the height direction Z of the pulse acquisition device 100. A receiving hole 101 is formed between the mounting base 12 and the base 11. The extending direction of the receiving hole 101 is parallel to the width direction Y of the pulse acquisition device 100. The receiving hole 101 is used to accommodate the wrist of the patient to be tested. The airbag module 31 is disposed on the mounting base 12 and located in the receiving hole 101. The detection module 32 is disposed on the airbag module 31. When the pulse acquisition device 100 detects the pulse, the patient's hand is inserted into the receiving hole 101, and the cun, guan, and chi positions on the wrist are aligned with the airbag module 31. When the airbag module 31 is inflated, it causes the detection module 32 to rest against the cun, guan, and chi positions on the wrist. The detection module 32 is used to detect the pressure changes during the pulse beat, thereby realizing the detection of the pulse signal.

[0045] The support member 40 includes a support portion 41 and two positioning portions 42. The support portion 41 is disposed on the base 11 and fixed relative to the base 11. Both positioning portions 42 are disposed on the side of the support portion 41 facing the mounting base 12. The two positioning portions 42 are located at two ends of the support portion 41 near the wall of the receiving hole 101. The two positioning portions 42 are spaced apart along the length X direction of the pulse acquisition device 100. The two positioning portions 42 and the support portion 41 enclose a support groove 401. The opening of the support groove 401 faces the mounting base 12 and communicates with the receiving hole 101. The support groove 401 is used to accommodate the wrist of the patient to be tested, and to support and position the wrist. On the one hand, when the patient places his wrist on the support 40, the cun, guan, and chi positions on the patient's wrist are automatically aligned with the detection module 32, so as to facilitate the detection module 32 in measuring the pulse signal and avoid the problem of large detection error caused by misalignment of the cun, guan, and chi positions with the detection module 32, thereby improving the ease of use of the pulse acquisition device 100. On the other hand, by limiting the patient's hand through the support 40, the shaking of the patient's hand can also be reduced when the pulse acquisition device 100 is testing the patient, thereby improving the accuracy of the pulse detection of the pulse acquisition device 100.

[0046] The receiving hole 101 is generally elliptical in shape to match the cross-sectional shape of the patient's wrist, thereby improving the fit between the airbag module 31 and the patient's wrist and thus improving the accuracy of pulse signal detection by the pulse acquisition device 100.

[0047] On the horizontal projection plane perpendicular to the height direction Z of the pulse acquisition device 100, the orthographic projection of the detection module 32 is located between the two positioning parts 42, so that after the patient places his wrist on the support part 41, the two positioning parts 42 limit the wrist and align the wrist with the detection module 32.

[0048] For example, the positioning part 42 and the support part 41 can be integrally formed to simplify the manufacturing and assembly processes of the support member 40. In some embodiments, the positioning part 42 and the support part 41 can also be independently arranged and fixedly connected together by means of bonding, snap-fitting, welding, etc.

[0049] Please refer to the following: Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 , Figure 7 This is a front view of the support member 40 provided in the embodiment of this application. Figure 8This is a top view of the support member 40 provided in this embodiment. The pulse acquisition device 100 includes a first side 102 and a second side 103 disposed opposite to the first side 102. The first side 102 faces the patient to be tested. The second side 103 faces away from the patient to be tested, i.e., towards the physician. Two positioning parts 42 are disposed at the ends of the support part 41 near the second side 103. Exemplarily, in this embodiment, on the projection plane perpendicular to the height direction Z of the pulse acquisition device 100, the orthographic projection of the support part 41 is approximately rectangular, and the two positioning parts 42 are disposed at the two corners of the support part 41 near the second side 103. In this way, by positioning and supporting the back of the patient's hand with the two positioning parts 42, the alignment of the cun, guan, and chi positions on the patient's wrist with the detection module 32 can be improved.

[0050] Along the direction from the base 11 toward the mounting base 12, the cross-sectional size of the positioning part 42 gradually decreases. Understandably, when the patient's hand is placed on the support part 41, the back of the hand is inclined on both sides along the length direction X of the pulse acquisition device 100. The gradually decreasing cross-sectional size of the positioning part 42 improves the fit between the positioning part 42 and the back of the patient's hand, thereby improving the positioning and support capabilities of the patient's hand, improving the alignment of the cun, guan, and chi positions on the wrist with the detection module 32, and improving the detection effect of the pulse acquisition device 100.

[0051] For example, in this embodiment, the distance between the two positioning parts 42 gradually decreases along the direction from the first side 102 to the second side 103, and the distance between the two positioning parts 42 gradually increases along the direction from the base 11 to the mounting base 12. Thus, on the one hand, along the direction from the mounting base 12 toward the base 11, the width of the support groove 401 gradually decreases along the length direction X of the pulse acquisition device 100. During the process of the patient placing their wrist on the support 40, the guiding effect of the positioning part 42 enables the cun, guan, and chi positions on the wrist to automatically align with the detection module 32, thereby improving the ease of use of the pulse acquisition device 100. On the other hand, the two positioning parts 42 have a larger gap at the end closest to the first side 102, which helps to reduce the obstruction effect of the positioning part 42 when the patient's hand is inserted into the receiving hole 101, reduce the discomfort of the positioning part 42, improve the comfort of using the pulse acquisition device 100, and allow the patient's wrist to be slightly raised, fully exposing the cun, guan, and chi positions on the wrist, improving the alignment with the detection module 32.

[0052] Each of the two positioning parts 42 is provided with a positioning surface 421, which is respectively positioned facing the center of the receiving hole 101 and is used to contact the back of the hand of the patient to be tested. The positioning surface 421 is set at an angle to the height direction Z and the length direction X of the pulse acquisition device 100, respectively. On the vertical projection plane perpendicular to the width direction Y of the pulse acquisition device 100, the side of the positioning surface 421 near the mounting base 12 (the oblique side near the center of the receiving hole 101) can be set at an angle of 45° to the length direction X of the pulse acquisition device 100, so that the positioning part 42 can have a good fit when contacting the wrist of the patient to be tested with different wrist sizes, and can allow the patient's wrist to be slightly raised to align with the detection module 32. In some embodiments, on the vertical projection plane perpendicular to the width direction Y of the pulse acquisition device 100, the angle between the side of the positioning surface 421 near the mounting base 12 and the length direction X of the pulse acquisition device 100 can be other angles, which are not specifically limited in this application. For example, on the vertical projection plane perpendicular to the width direction Y of the pulse acquisition device 100, the angle between the side of the positioning surface 421 near the mounting base 12 and the length direction X of the pulse acquisition device 100 can also be 30°, 32°, 34°, 35°, 36°, 38°, 40°, 42°, 44°, 46°, 48°, 50°, 52°, 54°, 55°, etc.

[0053] The connection between the positioning part 42 and the support part 41 is rounded to reduce the discomfort when the patient's hand is inserted into the support groove 401, thus improving comfort. The corner of the positioning part 42 away from the support part 41 is rounded to avoid sharp impacts between the positioning part 42 and the patient's hand, further improving comfort when the patient's hand contacts the positioning part 42. The two positioning parts 42 can be symmetrically arranged on the support part 41.

[0054] In some embodiments, the support member 40 is configured as an elastic member. The support member 40 is capable of elastic deformation under external force. Compared to configuring the support member 40 as a rigid member, configuring it as an elastic member allows the support member 40 to better conform to the patient's hand through elastic deformation when the patient places their hand on it, reducing any discomfort or discomfort and improving comfort. The support member 40 can be configured as a silicone support member, a rubber support member, a sponge support member, etc.

[0055] The shape of the support portion 41 facing the base 11 is adapted to the shape of the base 11 facing the mounting base 12, thereby improving the fit between the support portion 41 and the base 11 and ensuring a firm connection between them. Along the length direction X of the pulse acquisition device 100, the thickness of the support portion 41 near its two ends along the height direction Z of the pulse acquisition device 100 is less than the thickness of the support portion 41 near its middle along the height direction Z of the pulse acquisition device 100. On a projection plane perpendicular to the width direction Y of the pulse acquisition device 100, the orthographic projection of the support portion 41 is approximately crescent-shaped. The side of the support portion 41 facing the mounting base 12 is saddle-shaped to improve the matching degree between the shape of the support portion 41 and the shape of the patient's hand, thereby enhancing the comfort of using the support portion 41.

[0056] In this embodiment, the mounting base 12 is vertically adjustable relative to the base 11, and the positioning part 42 protrudes from the base 11 towards the mounting base 12. When the patient's hand is placed on the support part 41 and the physician pushes the mounting base 12 towards the base 11, the positioning part 42 can block and protect the patient's hand, preventing the hand from contacting the mounting base 12. This avoids the patient's hand being trapped in the gap between the mounting base 12 and the base 11, preventing injury to the patient's hand and improving the safety of the pulse acquisition device 100.

[0057] In some embodiments, a gap 43 is formed between the positioning part 42 and the wall of the receiving hole 101. This serves two purposes: firstly, when the patient places their hand on the support 40, the gap 43 provides deformation space for the positioning part 42, allowing it to deform under pressure, reducing pressure on the patient's hand, minimizing discomfort from the support 40, and improving comfort; secondly, when the mounting base 12 is raised or lowered relative to the base 11, the gap 43 keeps the positioning part 42 spaced from the mounting base 12, preventing interference between them. The positioning part 42 can extend along the length X of the pulse acquisition device 100 towards the side wall of the receiving hole 101, parallel to the height direction of the pulse acquisition device 100.

[0058] Please refer to the following: Figure 4 , Figure 6 and Figure 9 , Figure 9This is a cross-sectional view of the pulse acquisition device 100 provided in this application embodiment after removing a portion of its structure. In some embodiments, the pulse acquisition device 100 further includes a support sensor 44. The support sensor 44 is located between the base 11 and the support member 40 and is used to sense the pressure on the support member 40. The support sensor 44 is electrically connected to the control module 50. The pulse acquisition device 100 determines whether the wrist of the patient to be tested is placed on the support member 40 based on the detection signal of the support sensor 44. When the wrist of the patient to be tested is placed on the support member 40, under the action of gravity, the wrist of the patient to be tested squeezes the support sensor 44 through the support member 40, causing the output signal of the support sensor 44 to change. The support sensor 44 can be configured as a pressure sensor and is electrically connected to the first circuit board 51.

[0059] In some embodiments, a recessed groove 412 is provided on the side of the support member 40 facing the base 11. An abutment portion 413 protrudes from the groove wall on the side of the recessed groove 412 opposite to the base 11. The abutment portion 413 is used to abut against the supporting sensor 44. In this way, by providing the recessed groove 412, the thickness of the support member 40 at the position corresponding to the recessed groove 412 can be reduced, and the supporting effect of the base 11 on the position corresponding to the recessed groove 412 on the support member 40 can be eliminated. Therefore, when the support member 40 is subjected to external pressure, the position corresponding to the recessed groove 412 on the support member 40 can deform preferentially and to a greater extent than other positions. This can drive the abutment portion 413 to make a greater displacement, increase the pressure exerted by the abutment portion 413 on the supporting sensor 44, and improve the pressure detection sensitivity of the pulse acquisition device 100.

[0060] In some embodiments, the support member 40 has a boss 414 on the side facing the mounting base 12. The boss 414 is provided on the support member 41 and protrudes from the support member 41 towards the mounting base 12. The boss 414 is located on the side of the abutment portion 413 away from the base 11. Thus, on the one hand, when the patient places their wrist on the support member 40, the patient's hand will preferentially contact the boss 414 and exert pressure on it. This, through the combined action of the boss 414, the recess 412, and the abutment portion 413, improves the detection speed and sensitivity of the pulse acquisition device 100. On the other hand, providing the boss 414 also increases the thickness of the bottom of the recess 412 on the support member 40, improves the connection strength between the abutment portion 413 and other positions of the support member 40, reduces the risk of breakage of the support member 40 at the position of the recess 412, and extends the service life of the support member 40.

[0061] Please see Figure 10 , Figure 10This is a cross-sectional view of the pulse acquisition device 100 provided in this application after removing another part of its structure. The support member 40 and the base 11 are detachably connected to facilitate maintenance or replacement of the support member 40. If the support member 40 is damaged, it can be replaced individually without replacing the entire base 11, improving the maintainability of the pulse acquisition device 100 and reducing user costs. Exemplarily, the support member 40 and the base 11 are connected by an insertion joint along the arrangement direction between the base 11 and the mounting base 12, allowing the support member 40 to be disassembled or installed without the use of additional special tools, reducing the difficulty of disassembling and assembling the support member 40 and the base 11. One of the support member 40 and the base 11 is provided with a limiting pin 113, and the other is provided with a limiting groove 411. The limiting pin 113 is inserted into the limiting groove 411. The limiting pin 113 and the limiting slot 411 both extend along the arrangement direction between the base 11 and the mounting base 12, so as to facilitate the insertion of the support 40 onto the base 11 or its removal from the base 11.

[0062] Please refer to the following: Figure 2 , Figure 4 and Figure 11 , Figure 11 This is a cross-sectional view of the lifting module 20 provided in an embodiment of this application. In this embodiment, the mounting base 12 is height-adjustable relative to the base 11 to adjust the size of the receiving hole 101, thereby enabling the pulse acquisition device 100 to adapt to wrists of different sizes. The pulse acquisition device 100 also includes the lifting module 20. The lifting module 20 is connected to both the base 11 and the mounting base 12. When the mounting base 12 is raised or lowered relative to the base 11, the lifting module 20 is used to limit and guide the mounting base 12, keeping the mounting base 12 connected to the base 11 and preventing the mounting base 12 from detaching from the base 11.

[0063] The lifting module 20 includes a guiding mechanism 21 and a limiting mechanism 22. The guiding mechanism 21 includes a first guide member 211 and a second guide member 212 that slides with the first guide member 211. The first guide member 211 is fixedly connected to a base 11. The second guide member 212 is fixedly connected to a mounting base 12. The base 11 has a first receiving cavity 110. The mounting base 12 has a second receiving cavity 120. One end of the first guide member 211 extends into the first receiving cavity 110 and is fixedly connected to the base 11, while the other end of the first guide member 211 movably extends into the second receiving cavity 120. One end of the second guide member 212 extends into the second receiving cavity 120 and is fixedly connected to the mounting base 12, while the other end of the second guide member 212 movably extends into the first receiving cavity 110.

[0064] The limiting mechanism 22 is movably mounted on the mounting base 12. The limiting mechanism 22 has a first position state and a second position state relative to the mounting base 12. In the first position state, the limiting mechanism 22 is engaged with the first guide member 211, and the first guide member 211 is fixed relative to the second guide member 212. The mounting base 12 is in a non-rising state relative to the base 11. Movement of the mounting base 12 away from the base 11 is restricted. In the second position state, the limiting mechanism 22 is separated from the first guide member 211, and the first guide member 211 is movable relative to the second guide member 212. The mounting base 12 can move freely towards or away from the base 11.

[0065] In this embodiment, when a user (doctor, patient, or other relevant person) uses the pulse acquisition device 100 to test a patient, the limiting mechanism 22 is first positioned in the second position. The mounting base 12 is then pulled away from the base 11, enlarging the receiving hole 101. After the patient inserts their wrist into the receiving hole 101, the user pulls the mounting base 12 relative to the base 11 to a suitable position, ensuring the size of the receiving hole 101 matches the thickness of the patient's wrist. This maintains a suitable distance between the airbag module 31 and the detection module 32 and the patient's wrist. Then, the limiting mechanism 22 is placed in the first position, and the airbag module 31 of the pulse acquisition device 100 is inflated. After the airbag module 31 is inflated, it drives the detection module 32 to press against the cun, guan, and chi positions on the wrist of the patient to be tested. The detection module 32 is used to detect the pressure changes generated when the pulse of the patient to be tested beats, and converts the pressure changes into corresponding electrical signals, thereby realizing the measurement of pulse signals. After the detection is completed, the limiting mechanism 22 is placed in the second position, and the mounting base 12 is pulled away from the base 11 so that the wrist of the patient to be tested is pulled out of the receiving hole 101.

[0066] In this embodiment, the mounting base 12 and the base 11 are movably connected, forming a receiving hole 101. An airbag module 31 is mounted on the mounting base 12 and located within the receiving hole 101. A detection module 32 is mounted on the airbag module 31. A first guide 211 is fixedly connected to the base 11, and a second guide 212 is fixedly connected to the mounting base 12. The first guide 211 and the second guide 212 slide together. A limiting mechanism 22 is movably mounted on the mounting base 12. When the pulse acquisition device 100 is used to detect a patient, the limiting mechanism 22 is placed in a second position, separating it from the first guide 211. The first guide 211 is movable relative to the second guide 212. At this time, the mounting base 12 is movable relative to the base 11. The size of the receiving hole 101 can be adjusted by changing the distance between the mounting base 12 and the base 11, thus allowing the size of the receiving hole 101 to match different patients. The size of the patient's wrist is matched to reduce or eliminate the distance difference between the airbag module 31 and the detection module 32 and the wrists of different patients. After the patient's wrist is inserted into the receiving hole 101 and the distance between the mounting base 12 and the base 11 is adjusted, the limiting mechanism 22 is placed in the first position, so that the limiting mechanism 22 is engaged with the first guide 211. The first guide 211 is fixed relative to the second guide 212. At this time, the mounting base 12 is fixed relative to the base 11. The pulse acquisition device 100 inflates the airbag module 31, so that the airbag module 31 drives the detection module 32 to press against the cun, guan, and chi positions on the patient's wrist. By matching the size of the receiving hole 101 with the size of the patient's wrist, the pressure of the detection module 32 on the wrists of different patients can be consistent or similar, thereby reducing the error of the pulse signal detected by the pulse acquisition device 100 and improving the detection accuracy of the pulse acquisition device 100.

[0067] The limiting mechanism 22 includes a pressing structure 221 and a locking member 222. The pressing structure 221 is movably mounted on the mounting base 12 and exposed relative to the mounting base 12. The locking member 222 is movably disposed inside the mounting base 12. The pressing structure 221 is used to engage or disengage the locking member 222 from the first guide member 211. The user can move the locking member 222 by pressing the pressing structure 221. After the user presses down the pressing structure 221, the limiting mechanism 22 is in a second position. After the user releases the pressing structure 221, the limiting mechanism 22 is in a first position.

[0068] Multiple guiding mechanisms 21 are provided. These multiple guiding mechanisms 21 are distributed on both sides of the receiving hole 101. Multiple snap-fit ​​pieces 222 are provided, each corresponding to one of the guiding mechanisms 21. A pressing structure 221 is used to engage or disengage each snap-fit ​​piece 222 with the first guide piece 211 of the corresponding guiding mechanism 21. Thus, on the one hand, by having multiple guiding mechanisms 21 working together, the force balance during the lifting and lowering of the mounting base 12 relative to the base 11 can be improved, enhancing stability and smoothness. On the other hand, by having one pressing structure 221 drive multiple snap-fit ​​pieces 222 to move together, the pulse acquisition device 100 does not need to have multiple pressing structures 221, simplifying the structure of the pulse acquisition device 100 and reducing its manufacturing cost. Exemplarily, in this embodiment, two guiding mechanisms 21 and two snap-fit ​​pieces 222 are each provided, with the two guiding mechanisms 21 and two snap-fit ​​pieces 222 arranged at intervals along the length X direction of the pulse acquisition device 100. In some embodiments, the guide mechanism 21 and the card connector 222 may also be configured as three, four, etc.

[0069] The pressing structure 221 includes a button 2211 and a linkage 2213. The linkage 2213 is located within the second receiving cavity 120. The button 2211 and the linkage 2213 are fixedly disposed relative to each other. The button 2211 is exposed relative to the mounting base 12. The linkage 2213 is located inside the mounting base 12 and cooperates with multiple snap-fit ​​pieces 222 respectively, so as to drive the multiple snap-fit ​​pieces 222 to engage or disengage with their corresponding first guide pieces 211, thereby simplifying the structure of the pulse acquisition device 100. The button 2211 provides a pressing point for the user. Pressing the button 2211 can drive the linkage 2213 to move relative to the mounting base 12.

[0070] The linkage 2213 includes a first linkage part 2214 and a plurality of second linkage parts 2215. The first linkage part 2214 is used to abut or connect with the button 2211. Each second linkage part 2215 is detachably connected to the end of the first linkage part 2214. The number of second linkage parts 2215 is the same as the number of snap-fit ​​parts 222. The plurality of second linkage parts 2215 are arranged in a one-to-one correspondence with the plurality of snap-fit ​​parts 222. When the first linkage part 2214 moves relative to the mounting base 12, it drives the plurality of second linkage parts 2215 to move together relative to the mounting base 12, and through the plurality of second linkage parts 2215, it drives the plurality of snap-fit ​​parts 222 to engage or disengage with the first guide members 211 of the plurality of guide mechanisms 21. In this way, a first linkage part 2214 can drive the plurality of snap-fit ​​parts 222 to move together, simplifying the structure of the linkage 2213, reducing the production cost of the linkage 2213, and streamlining the structure of the pulse acquisition device 100. For example, in this embodiment, the first linkage part 2214 is generally C-shaped. The number of second linkage parts 2215 is set to two. The two second linkage parts 2215 are respectively connected to the two ends of the first linkage part 2214.

[0071] In some embodiments, the first linkage part 2214 is disposed in contact with the button 2211, and when the button 2211 is pressed, the button 2211 pushes the first linkage part 2214 to move towards the base 11. In some embodiments, the first linkage part 2214 and the button 2211 are connected and fixed together. The first linkage part 2214 and the button 2211 can be fixedly connected together by means of adhesive bonding, screwing, snap-fitting, welding, etc.

[0072] In some embodiments, the wear resistance of the first linkage part 2214 is less than that of the second linkage part 2215. The second linkage part 2215 is detachably connected to the first linkage part 2214, allowing for individual replacement of the second linkage part 2215 after wear, avoiding the need to replace the entire linkage component 2213 and reducing the later maintenance costs of the pulse acquisition device. In some embodiments, damping grease can be applied to the contact point between the second linkage part 2215 and the locking member 222 of the linkage component 2213 to provide sliding damping, improve the pressing feel of the button 2211, and provide lubrication and anti-wear properties, extending the service life of the second linkage part 2215 and the locking member 222. In some embodiments, lubricating grease can also be applied to the contact point between the second linkage part 2215 and the locking member 222 of the linkage component 2213 to reduce wear on the second linkage part 2215 and the locking member 222.

[0073] In some embodiments, the pulse acquisition device 100 further includes a guide post 2261 and a linkage reset member 2262. The guide post 2261 is fixed within the mounting base 12. The linkage member 2213 is provided with a guide hole 2217. The guide post 2261 passes through the guide hole 2217 and is used to guide the linkage member 2213, causing the linkage member 2213 to move along the height direction Z of the pulse acquisition device 100. The linkage reset member 2262 is sleeved on the guide post 2261 and elastically abuts against the side of the linkage member 2213 away from the button 2211. The linkage reset member 2262 is used to push the linkage member 2213 to move away from the base 11, so that the linkage member 2213 remains in contact with the button 2211. Wherein, when the button 2211 is in the released state, the linkage member 2213 abuts against the button 2211 by the elastic force provided by the linkage reset member 2262.

[0074] In some embodiments, the pulse acquisition device 100 further includes a button reset member 2212 disposed within the mounting base 12. The button reset member 2212 elastically abuts against the side of the button 2211 near the linkage member 2213. The button reset member 2212 provides an elastic force to the button 2211 to move in a direction away from the base 11. After the user releases the button 2211, the elastic force provided by the button reset member 2212 and the linkage reset member 2212 in the pulse acquisition device 100 enables the button 2211 to automatically reset to a state exposed relative to the mounting base 12, thereby facilitating the user to press the button 2211 again, and keeping the linkage member 2213 abutting against the button 2211 during the movement of the linkage member 2213 and the button 2211, avoiding loosening or shaking, and improving the user's pressing feel.

[0075] Please refer to the following: Figure 4 , Figure 11 as well as Figure 12 , Figure 12 yes Figure 4 Enlarged view at point I. In some embodiments, the snap-fit ​​member 222 is slidably connected to the mounting base 12. The mounting base 12 is provided with a slide groove 121 extending along the length direction X. The snap-fit ​​member 222 is slidably disposed within the slide groove 121. The linkage member 2213 is used to drive the snap-fit ​​member 222 to move along the slide groove 121. When the snap-fit ​​member 222 slides to one end of the slide groove 121 near the first guide member 211, it engages with the first guide member 211. When the snap-fit ​​member 222 slides to one end of the slide groove 121 away from the first guide member 211, it disengages from the first guide member 211.

[0076] In some embodiments, the snap-fit ​​member 222 is rotatably connected to the mounting base 12. One of the snap-fit ​​member 222 and the mounting base 12 is provided with a rotating shaft, and the other is provided with a shaft hole. The rotating shaft passes through the shaft hole, and the snap-fit ​​member 222 is rotatable relative to the mounting base 12 along the central axis of the rotating shaft. When the linkage member 2213 moves relative to the mounting base 12, the direction of the force exerted by the linkage member 2213 on the snap-fit ​​member 222 is offset from the central axis of the rotating shaft, so that the force exerted by the linkage member 2213 on the snap-fit ​​member 222 drives the snap-fit ​​member 222 to rotate around the central axis of the rotating shaft.

[0077] The snap-fit ​​component 222 has a first guide surface 2221 on the side near the pressing structure 221. When the limiting mechanism 22 transitions from the first position state to the second position state, the pressing structure 221 presses against the first guide surface 2221 and pushes the snap-fit ​​component 222 to separate from the first guide component 211. And / or, the pressing structure 221 has a second guide surface 2216 on the side near the snap-fit ​​component 222. When the limiting mechanism 22 transitions from the first position state to the second position state, the second guide surface 2216 presses against the snap-fit ​​component 222 and pushes the snap-fit ​​component 222 to separate from the first guide component 211.

[0078] In some embodiments, a first guide surface 2221 is provided on the side of the latch 222 near the pressing structure 221. The first guide surface 2221 is inclined relative to the height direction Z of the pulse acquisition device 100. The distance between the end of the first guide surface 2221 near the first guide member 211 and the pressing structure 221 is greater than the distance between the end of the first guide surface 2221 away from the first guide member 211 and the pressing structure 221. When the button 2211 pushes the linkage member 2213 to move towards the latch 222, the second linkage part 2215 abuts against the first guide surface 2221. The force exerted by the second linkage part 2215 on the latch 222 is parallel to the height direction Z of the pulse acquisition device 100. Through the guiding effect of the first guide surface 2221, the force exerted by the second linkage part 2215 on the latch 222 generates a component force along the length direction X of the pulse acquisition device 100. This component force pushes the latch 222 to move away from the first guide member 211. Thus, by setting the first guide surface 2221, the structure of the snap-fit ​​component 222 can be simplified, so that there is no need to set a complex transmission structure between the pressing structure 221 and the snap-fit ​​component 222, thereby reducing the production cost of the pulse acquisition device 100.

[0079] In some embodiments, a second guide surface 2216 is provided on the side of the pressing structure 221 near the latching member 222. The second guide surface 2216 is inclined relative to the height direction Z of the pulse acquisition device 100. The distance between the end of the second guide surface 2216 near the first guide member 211 and the latching member 222 is less than the distance between the end of the second guide surface 2216 away from the first guide member 211 and the latching member 222. When the button 2211 pushes the linkage member 2213 to move towards the latching member 222, the second guide surface 2216 abuts against the latching member 222. The force exerted by the second linkage member 2215 on the latching member 222 is parallel to the height direction Z of the pulse acquisition device 100. Through the guiding effect of the second guide surface 2216, the second guide surface 2216 can generate a component force on the latching member 222 along the length direction X of the pulse acquisition device 100. This component force pushes the latching member 222 to move away from the first guide member 211. Thus, by setting the second guide surface 2216, the structure of the linkage 2213 can be simplified, so that there is no need to set a complex transmission structure between the pressing structure 221 and the snap-fit ​​component 222, thereby reducing the production cost of the pulse acquisition device 100.

[0080] In some embodiments, the snap-fit ​​member 222 is provided with a first guide surface 2221 on the side near the pressing structure 221, and the pressing structure 221 is provided with a second guide surface 2216 on the side near the snap-fit ​​member 222, so as to increase the contact area between the pressing structure 221 and the snap-fit ​​member 222, reduce the pressure at the contact position between the pressing structure 221 and the snap-fit ​​member 222, thereby reducing the wear of the pressing structure 221 and the snap-fit ​​member 222, and extending the service life of the pressing structure 221 and the snap-fit ​​member 222.

[0081] In some embodiments, when the snap-fit ​​member 222 is rotatably connected to the mounting base 12, the snap-fit ​​member 222 may not have a first guide surface 2221, and the pressing structure 221 may not have a second guide surface 2216. The contact position between the pressing structure 221 and the snap-fit ​​member 222 is misaligned with the central axis of rotation of the snap-fit ​​member 222 relative to the mounting base 12. That is, the extension direction of the force exerted by the pressing structure 221 on the snap-fit ​​member 222 does not pass through the central axis of rotation of the snap-fit ​​member 222 relative to the mounting base 12. Thus, the torque formed by the pressing structure 221 on the snap-fit ​​member 222 drives the snap-fit ​​member 222 to rotate.

[0082] In some embodiments, the limiting mechanism 22 further includes a snap-fit ​​reset member 223. The snap-fit ​​reset member 223 elastically abuts against the mounting base 12 and the snap-fit ​​member 222, and provides a resilient force to the snap-fit ​​member 222 in a direction approaching the first guide member 211. The resilient force provided by the snap-fit ​​reset member 223 is used to automatically snap the snap-fit ​​member 222 and the first guide member 211 together when the button 2211 is released, thereby fixing the position of the mounting base 12 relative to the base 11 and preventing the mounting base 12 from moving freely relative to the base 11. The snap-fit ​​reset member 223 can be configured as a spring, torsion spring, clockwork, elastic rubber, etc. A limiting groove may be provided on the snap-fit ​​member 222, and the end of the snap-fit ​​reset member 223 is accommodated in the limiting groove. The limiting groove is used to fix the snap-fit ​​reset member 223 relative to the snap-fit ​​member 222, thereby preventing the snap-fit ​​reset member 223 from disengaging from the snap-fit ​​member 222.

[0083] In some embodiments, the snap-fit ​​member 222 is slidably connected to the mounting base 12, and the snap-fit ​​reset member 223 may be disposed on the side of the snap-fit ​​member 222 away from the first guide member 211. In some embodiments, when the snap-fit ​​member 222 is rotatably connected to the mounting base 12, the snap-fit ​​reset member 223 may be disposed on the side of the snap-fit ​​member 222 away from the first guide member 211, or disposed on the side of the snap-fit ​​member 222 away from the base 11, so as to push the snap-fit ​​member 222 to rotate toward the first guide member 211.

[0084] Please refer to the following: Figure 4 , Figure 12 , Figure 13 and Figure 14 , Figure 13 This is a cross-sectional view of the guide mechanism 21 provided in the embodiments of this application. Figure 14 This is a schematic diagram of the guiding mechanism 21 provided in this embodiment. In this embodiment, the second guide 212 is sleeved outside the first guide 211. The side wall of the second guide 212 has an opening 2121. The snap-fit ​​member 222 is movably inserted into the opening 2121 and is used to snap or separate from the first guide 211. When the limiting mechanism 22 is in the first position, the snap-fit ​​member 222 is inserted into the opening 2121. When the limiting mechanism 22 is in the second position, the snap-fit ​​member 222 can be located in the opening 2121, or the snap-fit ​​member 222 can also be located outside the opening 2121. In this embodiment, by sleeved the second guide 212 and the first guide 211 together, the structural size of the guiding mechanism 21 can be reduced, the space utilization of the guiding mechanism 21 can be improved, and it is beneficial to the miniaturization design of the pulse acquisition device 100. In some embodiments, the first guide 211 can be sleeved outside the second guide 212.

[0085] The second guide member 212 is provided with a guide through hole 2120. The first guide member 211 passes through the guide through hole 2120. The side of the guide through hole 2120 facing the base 11 is set as a clearance opening, and the first guide member 211 passes through the clearance opening into the guide through hole 2120.

[0086] In some embodiments, the first guide 211 is provided with a first limiting portion 2112. The second guide 212 is provided with a second limiting portion 2122. The first limiting portion 2112 and the second limiting portion 2122 cooperate to limit the first guide 211 in the guide through hole 2120, so as to prevent the first guide 211 from disengaging from the second guide 212. The second limiting portion 2122 is fixedly connected to one end of the second guide 212 near the base 11. The second limiting portion 2122 is fixed at the clearance opening. The first limiting portion 2112 is fixedly connected to one end of the first guide 211 near the mounting base 12. On a horizontal projection plane perpendicular to the arrangement direction of the base 11 and the mounting base 12, the orthographic projection of the first limiting portion 2112 and the second limiting portion 2122 at least partially overlap.

[0087] In some embodiments, the guiding mechanism 21 further includes a guiding reset member 213. The guiding reset member 213 elastically abuts between the first guide member 211 and the second guide member 212. The guiding reset member 213 provides an elastic force to the first guide member 211 and the second guide member 212 to separate them from each other. When the latching member 222 separates from the first guide member 211, it automatically pushes the first guide member 211 to move the mounting base 12 away from the base 11. This allows the mounting base 12 to automatically rise after the user presses the button 2211, facilitating one-handed operation of the pulse acquisition device 100 and improving the user experience. The guiding reset member 213 can be configured as a spring, elastic rubber, etc.

[0088] The first guide member 211 is provided with a receiving groove 2116. A guide reset member 213 is disposed within the receiving groove 2116. The receiving groove 2116 is used to limit the position of the guide reset member 213, thereby fixing its position and preventing it from moving around. In some embodiments, the second guide member 212 is provided with a guide post 2123, and the guide reset member 213 is sleeved on the outside of the guide post 2123. The guide reset member 213 is confined between the outer wall of the guide post 2123 and the inner wall of the receiving groove 2116.

[0089] The first guide 211 has a plurality of engaging parts 2113 on the side near the engaging part 222. The plurality of engaging parts 2113 are arranged at intervals along the arrangement direction of the base 11 and the mounting base 12. When the mounting base 12 is raised or lowered relative to the base 11 to a suitable position, the engaging part 222 engages with the corresponding engaging part 2113 to keep the mounting base 12 and the base 11 relatively fixed.

[0090] In this embodiment, the engaging portion 2113 is configured as a tooth, which protrudes from the surface of the first guide 211 facing the engaging member 222. In some embodiments, the engaging portion 2113 may also be configured as a hole, in which the engaging member 222 extends into the hole when engaging with the first guide 211.

[0091] When the limiting mechanism 22 is in the first position and the mounting base 12 is subjected to an external force in a direction away from the base 11, the locking member 222 engages with the locking part 2113, and the mounting base 12 and the base 11 are relatively fixed. In this way, when the mounting base 12 is adjusted to a suitable position relative to the base 11, the mounting base 12 and the base 11 can remain relatively fixed, and when the airbag module 31 is inflated, the reaction force generated by the airbag module 31 on the mounting base 12 will not cause the mounting base 12 to move relative to the base 11, so that the airbag module 31 can drive the detection module 32 to press against the wrist of the patient to be tested.

[0092] The snap-fit ​​portion 2113 is provided with a first snap-fit ​​surface 2114. When the mounting base 12 is subjected to an external force in a direction away from the base 11, the first snap-fit ​​surface 2114 abuts against the snap-fit ​​member 222. The first snap-fit ​​surface 2114 is configured as a plane perpendicular to the arrangement direction of the base 11 and the mounting base 12, or as an inclined surface inclined towards the base 11, or as an arc surface curved towards the base 11. When the snap-fit ​​portion 2113 is configured as a snap tooth, the surface of the snap tooth near the base 11 is configured as the first snap-fit ​​surface 2114. When the snap-fit ​​portion 2113 is configured as a snap hole, the hole wall on the side of the snap hole away from the base 11 is configured as the first snap-fit ​​surface 2114.

[0093] The side surface of the latching member 222 facing away from the base 11 is configured as a second latching surface 2222. When the mounting base 12 is subjected to an external force in a direction away from the base 11, the second latching surface 2222 is used to abut against the latching portion 2113. The second latching surface 2222 is configured as a plane perpendicular to the arrangement direction of the base 11 and the mounting base 12, or as an inclined surface tilted in a direction away from the base 11, or as an arc surface curved in a direction closer to the base 11.

[0094] When the limiting mechanism 22 is in the first position and the mounting base 12 is subjected to an external force in the direction of approaching the base 11, the locking part 2113 pushes the locking member 222 to move relative to the mounting base 12, and the mounting base 12 moves closer to the base 11. After the wrist of the patient to be tested is inserted into the receiving hole 101, the user can directly press the mounting base 12 to maintain a suitable distance between the mounting base 12 and the base 11. During the pressing process, it is not necessary to press the button 2211, thereby simplifying the operation of the pulse acquisition device 100 and making it convenient for the user.

[0095] In some embodiments, the latching portion 2113 is provided with a first guide surface 2115. Along the direction from the first guide 211 toward the latching member 222, the first guide surface 2115 is inclined or bent toward the base 11. When the mounting base 12 is subjected to an external force toward the base 11, the first guide surface 2115 abuts against the latching member 222. When the mounting base 12 is subjected to an external force toward the base 11, under the guiding action of the first guide surface 2115, the latching member 222 is subjected to a lateral thrust, causing the latching member 222 to move away from the first guide 211. After the mounting base 12 falls to a suitable position, the latching member 222 engages with another latching portion 2113 under the elastic force of the latching reset member 223. Wherein, when the latching portion 2113 is configured as a tooth, the surface of the tooth facing away from the base 11 is provided as the first guide surface 2115. When the snap-fit ​​part 2113 is configured as a snap-fit ​​hole, the hole wall on the side of the snap-fit ​​hole near the base 11 is configured as a first guide surface 2115.

[0096] In some embodiments, the end of the latching member 222 near the first guide member 211 is provided with a second guide surface 2223. When the mounting base 12 is subjected to an external force in the direction of approaching the base 11, the second guide surface 2223 abuts against the latching portion 2113. The second guide surface 2223 is provided on the side of the latching member 222 facing the base 11. Along the direction of the latching member 222 towards the first guide member 211, the second guide surface 2223 is inclined or bent in the direction away from the base 11. When the mounting base 12 is subjected to an external force in the direction of approaching the base 11, under the guiding action of the second guide surface 2223, the latching member 222 is subjected to a lateral thrust, causing the latching member 222 to move in the direction away from the first guide member 211. After the mounting base 12 falls to a suitable position, the latching member 222 engages with another latching tooth under the elastic force of the latching reset member 223. In some embodiments, the snap-fit ​​portion 2113 is provided with a first guide surface 2115, and the snap-fit ​​member 222 is provided with a second guide surface 2223. The first guide surface 2115 and the second guide surface 2223 are disposed opposite to each other and are used to abut against each other.

[0097] In some embodiments, the surface of the latching portion 2113 near the base 11 can be configured as a plane perpendicular to the arrangement direction of the base 11 and the mounting base 12, and / or, the surface of the latching member 222 near the base 11 can be configured as a plane perpendicular to the arrangement direction of the base 11 and the mounting base 12. When the limiting mechanism 22 is in the first position and the mounting base 12 is subjected to an external force in the direction toward the base 11, the latching member 222 engages with the latching portion 2113, and the mounting base 12 is fixed relative to the base 11. The user can adjust the mounting base 12 to move closer to or further away from the base 11 after pressing the button 2211.

[0098] Please refer to the following: Figure 4 and Figure 5 In some embodiments, the pulse acquisition device 100 also includes a power supply 57. The power supply 57 is disposed within the first receiving cavity 110 and electrically connected to the airbag module 31 and the detection module 32. The power supply 57 provides power to the pulse acquisition device 100, enabling it to perform pulse detection on the patient. In the pulse acquisition device 100 and diagnostic system 1000 provided in this application, on the one hand, the power supply 57 provides power to the airbag module 31 and the detection module 32 during pulse detection, allowing the pulse acquisition device 100 to be used wirelessly. This allows the pulse acquisition device 100 to perform pulse detection without being connected to a power outlet via a power cord, enabling it to be placed in different locations as needed, eliminating the limitations imposed by the power cord on its use, and improving its ease of use. On the other hand, by placing the power supply 57 within the base 11, the weight provided by the power supply 57 can increase the base's capacity. The weight ratio of the base 11 causes the overall center of gravity of the pulse acquisition device 100 to be closer to the base 11, thereby improving the stability of the pulse acquisition device 100 after placement, reducing the risk of the pulse acquisition device 100 tipping over when the patient's wrist is inserted into the receiving hole 101, increasing the stability of the pulse acquisition device 100 when performing pulse detection on the patient, thus preventing the detection module 32 from shaking relative to the wrist, improving the detection accuracy of the pulse signal, and reducing the risk of the pulse acquisition device 100 being knocked over by people or external objects when placed on the table, preventing the pulse acquisition device 100 from rolling off the table, and improving the safety of the pulse acquisition device 100 in use.

[0099] In some embodiments, the pulse acquisition device 100 further includes a control module 50. The control module 50 includes a first circuit board 51 and a second circuit board 52 electrically connected to the first circuit board 51. The first circuit board 51 is located in a first receiving cavity 110 and is fixedly connected to a base 11, and is electrically connected to a power supply 57. The second circuit board 52 is located in a second receiving cavity 120 and is fixedly connected to a mounting base 12, and is electrically connected to an airbag module 31 and a detection module 32. Thus, compared to the solution of setting a single circuit board, this embodiment, by setting a first circuit board 51 and a second circuit board 52, allows each circuit element in the control module 50 to have a larger installation area, improves the rationality of the circuit element arrangement, reduces the circuit design difficulty of the control module 50, and facilitates the heat dissipation of the circuit elements. Furthermore, by setting the first circuit board 51 in the first receiving cavity 110 and the second circuit board 52 in the second receiving cavity 120, the space in the pulse acquisition device 100 can be fully utilized, reducing space waste, and avoiding the problem of heat concentration caused by setting the first circuit board 51 and the second circuit board 52 in the same receiving cavity. This allows the first circuit board 51 and the second circuit board 52 to dissipate heat through the base 11 and the mounting base 12 respectively, improving the heat dissipation efficiency of the control module 50.

[0100] In some embodiments, the second circuit board 52 is provided with a clearance hole 521. The second circuit board 52 is located on the side of the linkage 2213 opposite to the base 11. The button 2211 passes through the clearance hole 521. The button 2211 is approximately positioned at the midpoint of the mounting base 12 along the width direction Y and length direction X of the pulse acquisition device 100. The button 2211 passing through the clearance hole 521 allows the second circuit board 52 to have a larger mounting area in the second receiving cavity 120, improving the layout rationality of the components on the second circuit board 52, increasing the space utilization rate in the pulse acquisition device 100, and preventing interference between the button 2211 and other structures in the pulse acquisition device 100.

[0101] In some embodiments, the pulse acquisition device 100 further includes a wireless communication module 56. The wireless communication module 56 is disposed in the first receiving cavity 110 and electrically connected to the first circuit board 51; alternatively, the wireless communication module 56 is disposed in the second receiving cavity 120 of the mounting base 12 and electrically connected to the second circuit board 52. The wireless communication module 56 is electrically connected to a power supply 57 to supply power to the wireless communication module 56. The wireless communication module 56 is used for wireless communication with the diagnostic device 200. Thus, compared to a wired connection between the pulse acquisition device 100 and the diagnostic device 200 via a signal cable, the pulse acquisition device 100 in this embodiment communicates with the diagnostic device 200 via the wireless communication module 56, eliminating the limitation of the signal cable on the usable space of the pulse acquisition device 100, enabling wireless use of the pulse acquisition device 100, expanding its application scenarios, and improving its ease of use. The diagnostic device 200 can be a mobile phone, computer, facial diagnostic instrument, etc. The wireless communication module 56 can be configured as a Bluetooth module, WiFi module, etc.

[0102] Please refer to the following: Figure 2 , Figure 4 and Figure 5 ,exist Figure 5 In the process, the components in the airbag module 31 and the detection module 32 are in a planar unfolded state. After the airbag module 31 and the detection module 32 are assembled, the shape of each component in the airbag module 31 and the detection module 32 can change according to the actual situation.

[0103] In this embodiment, the airbag module 31 includes an airbag body 311 and a protective layer 312. The airbag body 311 is disposed on the mounting base 12 and located in the receiving hole 101. The protective layer 312 is connected to the side of the airbag body 311 facing the base 11 and forms an accommodating space with the airbag body 311. The detection module 32 is disposed within the accommodating space. When the airbag body 311 is inflated, it moves the detection module 32 toward the base 11. When the air volume in the airbag body 311 reaches a certain level, the protective layer 312 is pressed tightly against the wrist of the patient to be tested, and the detection module 32 presses against the protective layer 312 at the corresponding cun, guan, and chi positions on the user's wrist. In this embodiment, the airbag body 311 drives the detection module 32 to contact the wrist of the patient to be tested. After the detection module 32 contacts the wrist, the elastic compression of the gas in the airbag body 311 avoids the problem of excessive or insufficient pressure on the detection module 32. This reduces the difficulty of pressure control of the detection module 32 by the pulse acquisition device 100, and eliminates the need for doctors to manually adjust the pressure. This reduces the difficulty of using the pulse acquisition device 100, reduces the complexity of the mechanical structure of the pulse acquisition device 100, and lowers the risk of failure of the pulse acquisition device 100.

[0104] Please see Figure 15 , Figure 15 This is an exploded view of the airbag module 31 and the detection module 32 provided in some embodiments of this application. In some embodiments, the pulse acquisition device 100 further includes an electromagnetic shield 323. In some embodiments, the detection module 32 and the protective layer 312 are isolated by the electromagnetic shield 323. The electromagnetic shield 323 is also disposed on the side of the detection module 322 near the protective layer 312. It is understood that in some cases, the body of the patient to be tested may carry static electricity. When the airbag module 31 comes into contact with the wrist of the patient to be tested, the static electricity can easily be conducted to the detection module 322 through the protective layer 312. In the embodiments of this application, the detection module 32 and the protective layer 312 are isolated by the electromagnetic shield 323. Through the blocking effect of the electromagnetic shield 323 on static electricity, damage to the detection module 322 by static electricity can be avoided, and signal interference caused by static electricity to the detection module 322 can be reduced, thereby improving the detection accuracy and reliability of the pulse acquisition device 100.

[0105] In some embodiments, the detection module 32 includes a plurality of detection elements 322. Adjacent detection elements 322 are isolated from each other by an electromagnetic shielding element 323, and / or the detection module 32 is isolated from the protective layer 312 by an electromagnetic shielding element 323. In some embodiments, the electromagnetic shielding element 323 provides electromagnetic shielding between the detection elements 322, preventing electromagnetic interference between different detection elements 322 and improving the detection accuracy of each detection element 322.

[0106] In some embodiments, two adjacent detection elements 322 are isolated by an electromagnetic shielding element 323, and the detection module 32 and the protective layer 312 are also isolated by an electromagnetic shielding element 323. The electromagnetic shielding element 323 can either wrap around the detection module 32 or wrap around each detection element 322 separately, thereby improving the electromagnetic protection effect of the electromagnetic shielding element 323 on the detection elements 322.

[0107] Please refer to the following: Figure 4 , Figure 15 and Figure 16 , Figure 16This is a schematic diagram of the support pad 321 provided in this embodiment. The detection module 32 includes the support pad 321 and the detection element 322. The support pad 321 is disposed on the side of the airbag body 311 facing the protective layer 312. The detection element 322 is disposed on the side of the support pad 321 facing the protective layer 312. The support pad 321 provides support for the detection element 322, allowing the detection element 322 to apply pressure to the wrist of the patient being tested to meet usage requirements. Because the airbag body 311 is elastic, the support force provided by the support pad 321 can resist the pressure acting on the detection element 322 during pulse beats, and prevents the pressure acting on the detection element 322 from being completely absorbed by the airbag body 311. This allows the detection element 322 to accurately detect the pulse beat on the wrist of the patient being tested, improving the detection accuracy of the detection element 322 and thus improving the reliability of the detection results of the pulse acquisition device 100. The support pad 321 and the electromagnetic shield 323 are also used to fix the detection element 322, preventing the detection element 322 from moving around in the accommodating space, thereby facilitating the alignment of the detection element 322 with the cun, guan, and chi positions on the wrist of the patient to be tested after the airbag body 311 is inflated.

[0108] In some embodiments, the support pad 321 includes a pad body 3211 and a protrusion 3212. The pad body 3211 is disposed on the side of the airbag body 311 facing the protective layer 312. The protrusion 3212 is disposed on the side of the pad body 3211 opposite to the airbag body 311, and the side of the protrusion 3212 opposite to the pad body 3211 is arc-shaped. A detection element 322 is disposed on the side of the protrusion 3212 opposite to the pad body 3211. In this embodiment, the side of the protrusion 3212 away from the pad body 3211 is arc-shaped. When the protrusion 3212 drives the detection element 322 to contact the wrist of the patient to be tested, the force exerted by the protrusion 3212 on the detection element 322 is located near the tangent point between the protrusion 3212 and the detection element 322. This allows the force exerted by the protrusion 3212 on the detection element 322 to be directed towards the blood vessels on the wrist, thereby enabling the detection element 322 to detect the optimal pulse signal on the blood vessels, improving the detection accuracy of the pulse signal by the detection element 322, and improving the reliability of the pulse detection results of the pulse acquisition device 100.

[0109] The gasket body 3211 and the protrusion 3212 can be integrally formed to simplify the manufacturing process of the support pad 321 and reduce production costs. In some embodiments, the gasket body 3211 and the protrusion 3212 can also be independently set and fixedly connected together by means of bonding, snap-fitting, welding, screwing, etc.

[0110] The support pad 321 includes three protrusions 3212. The three protrusions 3212 are arranged at intervals along the extending direction of the receiving hole 101. The detection module 32 includes three detection elements 322. Each of the three detection elements 322 corresponds to one of the three protrusions 3212. The three detection elements 322 correspond to the cun, guan, and chi positions on the wrist, respectively, and are used to detect pulse signals at these positions. Compared to setting three pad bodies 3211, where each of the three pad bodies 3211 is connected to a corresponding protrusion 3212, in this embodiment, by setting all three protrusions 3212 on one pad body 3211, the contact area between the pad body 3211 and the airbag body 311 can be increased, thereby increasing the stability of the pad body 3211 on the airbag body 311, reducing the shaking degree of the protrusions 3212, and thus providing stable support for the detection element 322, reducing the interference to the detection element 322 caused by the shaking of the protrusions 3212.

[0111] Each protrusion 3212 includes a plurality of sub-protrusions 3213. The plurality of sub-protrusions 3213 are arranged in a direction perpendicular to the extension direction of the receiving hole 101. The arrangement direction of the plurality of sub-protrusions 3213 is parallel to the length direction X of the pulse acquisition device 100. Each sub-protrusion 3213 is spherically shaped on the side opposite to the pad body 3211. Thus, on the one hand, by making the side of the sub-protrusion 3213 facing away from the pad body 3211 spherical, the sub-protrusion 3213 tangentially abuts against the detection element 322, making the force exerted by the sub-protrusion 3213 on the detection element 322 perpendicular to the wrist vessels, improving the accuracy of the detection element 322 in detecting vessel pressure. On the other hand, by setting multiple sub-protrusions 3213, the coverage length of the detection element 322 along the length direction X of the pulse acquisition device 100 can be increased, thereby improving the alignment degree between the detection element 322 and the cun, guan, and chi positions when the detection element 322 contacts the wrist of the patient being tested, reducing the alignment difficulty, and avoiding the problem of misalignment between the detection element 322 and the cun, guan, and chi positions. The side of the sub-protrusion 3213 facing away from the pad body 3211 can be spherical or ellipsoidal. The number of sub-protrusions 3213 in each protrusion 3212 can also be set to other numbers according to actual needs, which are not specifically limited in this application. For example, the number of sub-protrusions 3213 in each protrusion 3212 can be set to three.

[0112] Please see Figure 15In some embodiments, the electromagnetic shield 323 is configured to enclose each detection element 322. The electromagnetic shield 323 also provides cushioning for the detection element 322, preventing bending and wear of the detection element 322 due to rigid contact with the protrusion 3212, thereby improving the detection accuracy of the detection element 322 and extending its service life. The electromagnetic shield 323 can be constructed with a bag-like structure, with the detection element 322 disposed inside the electromagnetic shield 323.

[0113] In this embodiment, the detection module 32 is configured as a piezoelectric detection module, and the detection element 322 is configured as a piezoelectric sensor to improve the sensitivity and detection accuracy of the detection element 322. In some embodiments, the detection element 322 may also be configured as other types of sensors, such as a piezoresistive sensor, a capacitive sensor, etc.

[0114] In this embodiment, two detection modules 32 are configured. The two detection modules 32 are arranged at intervals along a direction perpendicular to the extension direction of the receiving hole 101. Each detection module 32 contains three detection elements 322. One of the two detection modules 32 is positioned on the airbag body 311 corresponding to the cun, guan, and chi positions on the left wrist of the patient being tested, and the other of the two detection modules 32 is positioned on the airbag body 311 corresponding to the cun, guan, and chi positions on the right wrist of the patient being tested. By configuring two detection modules 32, the pulse acquisition device 100 in this embodiment can perform pulse detection on the left and right hands of the patient being tested separately. Furthermore, when switching wrists, it is not necessary to reverse the direction of use of the pulse acquisition device 100; simply moving the pulse acquisition device 100 is sufficient to complete the detection on different wrists, thus improving the ease of use and measurement efficiency of the pulse acquisition device 100 and shortening the measurement time.

[0115] Please refer to the following: Figure 15 and Figure 17 , Figure 17 This is a schematic diagram of the pulse acquisition device 100 provided in this application embodiment after removing one part of the structure. The airbag module 31 also includes an air pump 33, a control valve 34, and an air tube (not shown in the figure). The air pump 33 and the control valve 34 are respectively disposed inside the mounting base 12. The air tube connects the air pump 33 and the control valve 34, and connects the control valve 34 and the airbag body 311. The air pump 33 is used to inflate the airbag body 311 through the air tube, so that the airbag body 311 inflates. The control valve 34 is used to control the opening and closing of the air tube, so that the air pump 33 pushes gas into the airbag body 311 or the gas in the airbag body 311 is discharged from the airbag body 311. In some embodiments, the airbag module 31 also includes a pipe connector for communicating with multiple air tubes, so that the multiple air tubes are connected together.

[0116] In some embodiments, the airbag module 31 further includes a pressure detection element 35, which is used to detect the air pressure inside the airbag body 311. The control module 50 is electrically connected to the pressure detection element 35. The pressure detection element 35 may be mounted on the second circuit board 52. The detection end of the pressure detection element 35 is connected to the airbag body 311 via an air tube to detect the air pressure inside the airbag body 311. The control module 50 is also used to determine the air pressure inside the airbag body 311 based on the air pressure signal detected by the pressure detection element 35, so that when the air pressure inside the airbag body 311 reaches a preset air pressure value, it controls the air pump 33 to stop inflating the airbag body 311, or controls the control valve 34 to close the air tube connected to the airbag body 311. Compared to the method of manually pumping air into the airbag body, in this embodiment, the pulse acquisition device 100 inflates the airbag body 311 through the air pump 33 and controls the inflation and deflation of the airbag body 311 through the control module 50. This avoids the doctor manually squeezing the inflatable airbag to inflate the airbag body 311, improves the automation level of the pulse acquisition device 100, reduces the operation difficulty of the pulse acquisition device 100, enhances the user experience, and makes the structure of the pulse acquisition device 100 more concise and aesthetically pleasing.

[0117] Please refer to the following: Figure 2 and Figure 4 In some embodiments, the pulse acquisition device 100 further includes an adsorption member 60. The adsorption member 60 is disposed on the side of the base 11 opposite to the mounting base 12. When the pulse acquisition device 100 is placed on the support surface 300 (e.g., a tabletop), the adsorption member 60 adsorbs onto the support surface 300. On the one hand, this improves the stability of the pulse acquisition device 100 when placed on the support surface 300, reduces the risk of the pulse acquisition device 100 tipping over when the patient's wrist is inserted into the receiving hole 101, increases the stability of the pulse acquisition device 100 when performing pulse detection on the patient, avoids the pulse acquisition device 100 sliding or shaking relative to the support surface 300, which could interfere with the detection signal of the detection module 32, reduces the detection error during pulse detection, and improves the reliability of the pulse detection results of the pulse acquisition device 100. This design improves reliability and reduces the risk of the pulse acquisition device 100 being knocked over by people or objects when placed on the support surface 300, preventing the pulse acquisition device 100 from rolling off the support surface 300 and improving the safety of the pulse acquisition device 100. On the other hand, when it is necessary to pull the mounting base 12 away from the base 11, the suction force provided by the suction member 60 adhering to the support surface 300 can prevent the pulse acquisition device 100 from being lifted off the support surface 300 when the user can only lift the mounting base 12 with one hand due to inconvenience of both hands. This allows the user to operate the pulse acquisition device 100 with one hand, improving the ease of use of the pulse acquisition device 100.

[0118] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
